A smart lock replaces or augments a mechanical lock so a door can be opened by fingerprint, PIN, card, app or a temporary code instead of a physical key. Xingliao, a Shenzhen manufacturer founded in 2014 with 110 staff, supplies smart lock OEM programmes with fingerprint, RFID and app-based models.

  • Unlocking: fingerprint, PIN, RFID card and app
  • Access codes: temporary and one-time codes for rentals and hotels
  • Fitting: cylinder and mortise options for EU and US doors
  • Programme: from 500 pcs, NDA signed by default

A smart lock replaces the keyed cylinder with an electronic lock that opens by fingerprint, PIN code, card, phone or remote command while keeping a physical key as the fallback. We supply select smart lock models alongside our switches, cameras and sensors, so distributors working with us on smart hardware can cover the front door from the same factory rather than opening a second supplier relationship.

What a Smart Lock Actually Replaces

Most buyers ask whether the lock replaces the whole door. It usually does not: it replaces the lock body or its outer trim. The door, frame and existing cut-out stay, which is why door thickness, mortise size and bore diameter decide whether a given model fits. Getting those three numbers wrong is the single reason a shipment ends up unsellable in a new market.

Because our main range sits in switches, sensors and doorbells rather than locks, we keep this line focused on the configurations distributors ask for most, and we will tell you plainly when another supplier's model fits your requirement better than ours.

Lock Types Available

  • Fingerprint door lock — capacitive or optical reader with stored templates, the most requested configuration for residential front doors.
  • PIN keypad lock — numeric code entry, widely used for short-let properties because codes can be changed between guests.
  • Card and tag versions — RFID access for small offices and managed buildings.
  • Wi-Fi remote lock — unlocking and temporary codes from the Tuya or Smart Life app.
  • Retrofit cylinder — a replacement cylinder that keeps existing handles, aimed at markets where full lock replacement is uncommon.

Which Type Fits Which Buyer

Configuration Best for Notes for distributors
Fingerprint Owner-occupied homes, premium residential Highest perceived value; confirm reader is anti-spoof (live-finger detection) for the markets you sell into.
PIN keypad Holiday rentals, serviced apartments, dorms Codes changed per guest; pair with an audit log if the customer manages many units.
Card / tag Offices, co-working, care homes Simple to issue and revoke; no app training needed for staff.
Wi-Fi remote Landlords, remote family access Needs 2.4 GHz Wi-Fi; Tuya / Smart Life gives temporary codes and an activity log.
Retrofit cylinder Markets where full replacement is rare Keeps the existing handle; shortest path to a "smart" listing without new door prep.

Fitting: The Numbers to Confirm First

  1. Door thickness — the range the lock clamps onto, which varies by housing type.
  2. Mortise standard and backset — whether the local standard matches the lock body supplied.
  3. Bore diameter — existing cross-bore and edge-bore dimensions on the door.
  4. Handing — whether the unit needs to be specified left or right, or is reversible.
  5. Power and fallback — battery type, low-battery warning, emergency key and external emergency charging.

Send these five points with your target market and we confirm whether an existing model fits before you commit to sampling.

Specs to Confirm With the Factory

Parameter What to check
Door thickness Typical fit range 35–55 mm; confirm the extremes your market needs before quoting.
Mortise / backset Common backsets are 60 mm and 70 mm; mismatch is the usual cause of returns.
Power 4× AA alkaline or a rechargeable lithium cell, with low-battery warning and a USB-C emergency charge port.
Weather protection Exterior-rated units should state an IP rating (IP54 indoor-adjacent, IP65 for exposed outdoor doors).
Certifications CE, FCC and RoHS as baseline; UKCA, CCC and PSE depend on the destination market.
Minimum order Standard configurations begin at 500 pieces per model, with logo and packaging customisation available.

Ecosystem Options

  • Tuya / Smart Life — remote unlocking, temporary codes and an activity log through the app many of your customers already use.
  • Standalone operation — fingerprints and codes stored locally on the lock for customers who do not want cloud connectivity.
  • Voice announcements and scenes — where paired within a broader system such as our smart home automation range.

Volume, Branding and Honest Limits

Standard configurations begin at 500 pieces per model, with logo application, custom retail packaging and multilingual documentation available as with our other lines. Because this is a focused line rather than a full lock programme, very specialised requirements such as unusual mortise standards or heavy commercial certification are better sourced from a dedicated lock factory — we will say so early rather than quote and disappoint.

Frequently Asked Questions

Do you make fingerprint locks as well as keypad models?

Yes. Fingerprint, PIN keypad, card and Wi-Fi remote versions are available, plus retrofit cylinders for markets where replacing the full lock is uncommon.

Will it fit doors in our market?

That depends on door thickness, mortise standard, backset and bore diameter. Send those four numbers and we confirm the fit, or tell you if another supplier's model suits better.

Is there still a physical key?

Yes. Mechanical key override plus emergency external charging are retained, since markets without them tend to reject electronic-only locks.

Can temporary access codes be issued remotely?

Yes on Tuya and Smart Life models, which is why these configurations suit holiday rentals and serviced apartments.

What is the minimum order quantity?

Standard configurations begin at 500 pieces per model, with logo and packaging customisation available at that volume.

What certification comes with shipments?

CE, FCC and RoHS documentation with the test reports needed for import. Additional scheme-specific approvals depend on the lock configuration and are quoted case by case.

What IP rating should an outdoor smart lock have?

For doors exposed to weather, look for IP65 on the exterior reader; IP54 is acceptable for sheltered entrances. We state the rating per model so your listing matches the unit shipped.

What happens when the battery dies?

The lock keeps a mechanical key override and a USB-C emergency charge port, so a dead battery never locks someone out permanently. Low-battery warning is shown in the app and on the keypad before power runs out.
